Last week I had workshop on CARNet User Conference on topic of ZFS on Linux. In it, I tried to describe my experience with it, from zfs-fuse days up until today. There are quite a few useful bits in this presentation, covering everything from history and basic ZFS concepts up to smart hints and some downsides. I hope it was useful to people who attended it and that you, dear reader, will find something useful in presentation which is embedded below.
